A. 8.8 students per day on average were absent.
1) If the absence recorded was:
On Monday: 11
On Tuesday: 9
On Wed: 6
On Thu: 9
On Fri: 9
2) Since the number of weekdays were 5 we can calculate the mean of absent students by adding all those absences and dividing by 5
So, 11+9+6+9+9+9 =44
Dividing by 5
So the mean or the average of the absence was 8.8
P(400<x<450)
P( (400-400)/50 < Z< (450-400)/50)
P (0 <z< 1) = 0.8413 -0.500=0.3413 = 34.13%
First, It's a function.
Second, domain is {a,b,c,d}
Third, range is {x,y,z}
Reason why it's function because
1. A single value in Input doesn't have 2 lines connected (domain must not be repetitive.)
2. All Inputs have lines connected to Output (if not then not a function.)
